summary
ZW43-12(F) outdoor high voltage (intelligent) vacuum circuit breaker is an outdoor high voltage switchgear with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short circuit current of power system. It is suitable for protection and control of substation, industrial and mining enterprises and urban and rural distribution network, especially for places with frequent operation and urban automation distribution network. Meet the following standards:
GB / T1984 high voltage alternating current circuit breakers, GB / T11022 high voltage switchgear
Common technical requirements with control equipment standard, DI402 AC high voltage break
Technical conditions for ordering road equipment
Model and its meaning
Product features
The vacuum arc extinguishing chamber adopts the patented sealing technology, with small volume, long service life, high reliability and exposed shield cover; it is sealed in the epoxy resin, with good weather resistance and convenient transportation;
The operating mechanism adopts high reliability bistable permanent magnet technology, which has simple structure and no need of maintenance. The mechanical life can reach 30000 times;
Epoxy resin packaging: meet the environmental protection requirements; have been widely verified outdoor performance; ozone and UV resistance; strong, light, not easy to break;
Permanent magnet mechanism: less moving parts; no maintenance; application of bistable permanent magnet technology;
Vacuum arc extinguishing, solid insulation, small volume, light weight, large breaking capacity, high insulation level;
Manual opening device: in case of control system failure, manual opening can be used as emergency opening operation to reliably open rated load current;
Position detector: the proximity switch is installed on the linkage shaft and does not need mechanical components. It is simple and reliable to detect the opening and closing position of the switch;
The switch shell is made of stainless steel or spray plastic, with good corrosion resistance and climate resistance;
Isolating switch, forming visible fracture and reliable interlock, forming combined electrical equipment;
The controller realizes the functions of remote control, telemetry, remote signaling and remote adjustment.
